Abstract (en)

[origin: EP0767049A2] A biaxially oriented polyester film for use in producing containers comprises (1) a polyester containing 93 mol% or more of ethylene terephthalate units as a component, having a breaking elongation in the machine direction (S MD) and a breaking elongation in the transverse direction (S TD) satisfying ÄFormula 1Ü and ÄFormula 2Ü, or (2) a polyester containing 93 mol% or more of ethylene terephthalate units as a component and having a face orientation coefficient of from 0.01 to less than 0.13, or (3) a polyester containing 95 mol% or more of ethylene terephthalate units as a component and having an amorphous Young's modulus of from 120 to 220 kg/mm<2>. Since the film has excellent formability, impact resistance and taste property, it is especially suitable as a film on both the inner and outer faces of metallic cans. <MATH> S MD: Breaking elongation in the machine direction S TD: Breaking elongation in the transverse direction <MATH>
